3 · Recommended Software Architecture

Entity Resolution & Intercompany Consolidation Platform

A single system replaces the workbook. Shared modules are deduplicated across hazards; each card shows how many of the selected hazards it resolves.

Deterministic Architecture (After)Golden Door Standard
Source systems (API / feed)
ERP / General LedgerGL, subledger, and master-data API with journal postingFX Rate ProviderDaily published-rate API with source attribution
Layer 1 · Ingestion
Integration & Ingestion Layer
2/7 hazards
Pulls transactions, balances, and master records directly from source-system APIs and file feeds, replacing every manual export.
Layer 2 · Master Data
Entity Resolution & Master Data Service
5/7 hazards
Maintains one canonical record per vendor, customer, legal entity, or contract and resolves aliases, subsidiaries, and duplicates deterministically.
Layer 3 · Validation & Matching
Reconciliation & Matching Engine
1/7 hazards
Matches records across two or more systems on amount, date window, and reference and isolates everything that does not match.
Rules & Assertion Engine
6/7 hazards
Evaluates deterministic control rules on every record before it can proceed, so a failed assertion blocks the transaction instead of a person catching it later.
Layer 4 · Exceptions & Approvals
Exception Management Queue
1/7 hazards
Routes every failed assertion or unmatched item to an owner with the evidence attached, and tracks it to resolution.
Approval Workflow
1/7 hazards
Enforces role-based, limit-based approvals inside the system so that decisions are recorded where the transaction lives, not in email or chat.
Layer 5 · Posting
Automated Ledger Posting
7/7 hazards
Posts balanced, validated entries to the ERP through its API so nothing is retyped and every entry carries its source lineage.
Layer 6 · Reporting & Evidence
Governed Reporting Layer
1/7 hazards
Publishes reports, board metrics, and monitoring dashboards from reconciled data only, with each figure traceable to its ledger snapshot.
Immutable Audit Log
1/7 hazards
Records every load, rule evaluation, approval, and posting in an append-only log so auditors can trace any figure to who did what and when.
4 · Solution Modules

What each component does, and what it needs

Modules are reusable across hazards. Inputs, outputs, enforced controls, and the point where a person still decides are listed for each.

Integration & Ingestion Layer
Layer 1 · Mapped from selection
2 of 7

Pulls transactions, balances, and master records directly from source-system APIs and file feeds, replacing every manual export.

Capabilities
  • Scheduled and webhook-driven API pulls
  • Idempotent loads keyed on source record IDs
  • Schema validation on every payload
Inputs
  • Read credentials for each source system
  • Field mapping per source
Outputs
  • Normalized transaction and master-data tables with source lineage
Controls enforced
  • Rate assertion: every translated balance must reference a stored rate record whose date and type (closing, average, historical) match the account's policy class, or the revaluation does not post.
  • Rate freshness: a revaluation run halts when any currency lacks a rate for the period-end date.
  • Equity assertion: the consolidated translation adjustment must equal the sum of per-entity adjustments computed from stored historical and closing rates, and consolidation cannot finalize while the equity section is out of balance.
  • Component integrity: an equity component without a stored historical rate blocks the translation run for its entity.
Human review: Approving new source connections and field mappings.

Entity Resolution & Master Data Service
Layer 2 · Mapped from selection
5 of 7

Maintains one canonical record per vendor, customer, legal entity, or contract and resolves aliases, subsidiaries, and duplicates deterministically.

Capabilities
  • Tax ID, bank-account, and legal-name uniqueness checks
  • Alias and parent-entity resolution rules
  • Golden-record propagation back to ERP, procurement, and billing
Inputs
  • Vendor, customer, and entity masters from each system
  • Contract and registration documents
Outputs
  • Canonical entity IDs referenced by every downstream module
Controls enforced
  • Intercompany zero-sum assertion: eliminating entries must balance to zero before group balance sheet generates.
  • Entity onboarding: adding a subsidiary registers it in the entity graph without touching any formula.
  • Elimination assertion: every intercompany receivable must have an equal and opposite payable at the counterparty entity before consolidation runs.
  • Policy-driven markups: intercompany percentages come from one policy table, never a per-entity cell.
  • Mapping assertion: every active subsidiary account must resolve to exactly one group account and segment set before its balance enters consolidation, or the run stops with the unmapped list.
  • Mapping change control: remapping an account requires approval and preserves the prior mapping for restatement.
  • Bilateral assertion: every intercompany transaction must have matched entries in both entities at the agreed rate and amount before the period closes, and unmatched items block consolidation with the counterparty listed.
  • Rate agreement: both sides of a transaction use the hub's stored rate for the transaction date, never an entity-local lookup.
Human review: Confirming proposed merges when two records match on some but not all identifiers.

Capabilities
  • Two-, three-, and multi-way matching
  • Configurable tolerance and date windows
  • Partial and many-to-one match handling
Inputs
  • Normalized transactions from each side of the match
  • Canonical entity IDs
Outputs
  • Matched sets, unmatched items, and variance explanations
Human review: Clearing unmatched items that fall outside tolerance.
Hazards resolved
#77Manual matching of intercompany charges across foreign subsidiaries
Rules & Assertion Engine
Layer 3 · Mapped from selection
6 of 7

Evaluates deterministic control rules on every record before it can proceed, so a failed assertion blocks the transaction instead of a person catching it later.

Capabilities
  • Versioned rule definitions with effective dates
  • Balance, threshold, and completeness assertions
  • Pass/fail evidence stored per record
Inputs
  • Normalized records
  • Policy thresholds and limits
Outputs

Controls enforced
  • Reconciliation assertion: local GAAP equity must equal group GAAP equity plus posted adjustment entries for every entity and period, and a statutory pack can only generate when that reconciliation holds.
  • Filing calendar: each entity's statutory deadline drives a readiness check that lists open reconciling items.
Human review: Changing a rule or threshold requires a documented approval.

Capabilities
  • Owner assignment by rule and department
  • Aging and escalation timers
  • Resolution codes with required evidence
Inputs
  • Assertion failures and unmatched items
Outputs
  • Resolved exceptions with disposition and approver
Human review: Every exception is dispositioned by a named owner; the system never auto-clears one.

Approval Workflow
Layer 4 · Mapped from selection
1 of 7

Enforces role-based, limit-based approvals inside the system so that decisions are recorded where the transaction lives, not in email or chat.

Capabilities
  • Role and limit matrices
  • Dual control for high-value or high-risk actions
  • Signed, time-stamped approval records
Inputs
  • Approval policy and authorized roles
  • Transactions requiring release

Layer 5 · Mapped from selection
7 of 7

Posts balanced, validated entries to the ERP through its API so nothing is retyped and every entry carries its source lineage.

Capabilities
  • Balanced double-entry generation
  • Idempotent posting with duplicate suppression
  • Subledger-to-GL tie-out on every batch
Inputs
  • Assertion-passed records
  • Chart of accounts and mapping rules
Outputs
  • ERP journal entries with source references
Human review: Period lock and close sign-off remain manual approvals.

Layer 6 · Mapped from selection
1 of 7

Records every load, rule evaluation, approval, and posting in an append-only log so auditors can trace any figure to who did what and when.

Capabilities
  • Append-only event history
  • Hash-chained records
  • Evidence export for external audit
Inputs
  • Events from every other module
Outputs
  • Audit-ready evidence trail
Human review: Auditors and controllers read the log; no one edits it.

5 · Control Matrix

Traceability from hazard to automated control

Each selected hazard maps to the module that resolves it, the deterministic rule that replaces the manual check, and the result once the rule is enforced.

HazardSoftware moduleAutomated controlResult
#08One tab per entity
Entity Resolution & Master Data Service
Intercompany zero-sum assertion: eliminating entries must balance to zero before group balance sheet generates.
Entity onboarding: adding a subsidiary registers it in the entity graph without touching any formula.
Consolidation and eliminations run from the entity graph; new entities do not break the rollup.
#15Intercompany markup & transfer pricing calculated manually
Entity Resolution & Master Data Service
Elimination assertion: every intercompany receivable must have an equal and opposite payable at the counterparty entity before consolidation runs.
Policy-driven markups: intercompany percentages come from one policy table, never a per-entity cell.
Paired intercompany entries eliminate to zero before consolidation runs.
#22Manual FX rate conversion revaluations across 8 foreign subsidiaries
Integration & Ingestion Layer
Rate assertion: every translated balance must reference a stored rate record whose date and type (closing, average, historical) match the account's policy class, or the revaluation does not post.
Rate freshness: a revaluation run halts when any currency lacks a rate for the period-end date.
Translation adjustments derive from stored policy rates; the equity section balances on every consolidation run.
#42Manual chart of accounts segment mapping across acquired companies
Entity Resolution & Master Data Service
Mapping assertion: every active subsidiary account must resolve to exactly one group account and segment set before its balance enters consolidation, or the run stops with the unmapped list.
Mapping change control: remapping an account requires approval and preserves the prior mapping for restatement.
Acquired charts resolve to the group chart through a governed graph; consolidation no longer waits on a bridge sheet.
#77Manual matching of intercompany charges across foreign subsidiaries
Entity Resolution & Master Data Service
Bilateral assertion: every intercompany transaction must have matched entries in both entities at the agreed rate and amount before the period closes, and unmatched items block consolidation with the counterparty listed.
Rate agreement: both sides of a transaction use the hub's stored rate for the transaction date, never an entity-local lookup.
Intercompany charges post to both entities from one record; the consolidated close no longer waits on elimination plugs.
#78Manual consolidation of statutory financial statements for overseas entities
Rules & Assertion Engine
Reconciliation assertion: local GAAP equity must equal group GAAP equity plus posted adjustment entries for every entity and period, and a statutory pack can only generate when that reconciliation holds.
Filing calendar: each entity's statutory deadline drives a readiness check that lists open reconciling items.
Statutory packs generate from parallel ledgers with posted adjustments; overseas filings stop running late.
#94Manual calculation of foreign currency translation adjustments on equity
Integration & Ingestion Layer
Equity assertion: the consolidated translation adjustment must equal the sum of per-entity adjustments computed from stored historical and closing rates, and consolidation cannot finalize while the equity section is out of balance.
Component integrity: an equity component without a stored historical rate blocks the translation run for its entity.
Translation adjustments post per entity from stored rates; the equity section balances without a plug.

7 · Where People Still Decide

Human approval points the system preserves

Deterministic software removes re-keying and eyeballing. It does not remove judgment; these are the decisions that stay with your team.

  • Integration & Ingestion Layer: Approving new source connections and field mappings.
  • Entity Resolution & Master Data Service: Confirming proposed merges when two records match on some but not all identifiers.
  • Reconciliation & Matching Engine: Clearing unmatched items that fall outside tolerance.
  • Rules & Assertion Engine: Changing a rule or threshold requires a documented approval.
  • Exception Management Queue: Every exception is dispositioned by a named owner; the system never auto-clears one.
  • Approval Workflow: Approvers act on the request; the workflow only enforces who and how many.
  • Automated Ledger Posting: Period lock and close sign-off remain manual approvals.
  • Governed Reporting Layer: Report release still requires reviewer sign-off; the layer prevents unreconciled figures from being publishable.
  • Immutable Audit Log: Auditors and controllers read the log; no one edits it.
